Remote desktop mstsc does not let go from under win10, how to solve?

Question

Remote Desktop

I'm moving from the seventh Windows to the ten, I'm trying to run MSTSC on the new computer to the desired remote server on Windows. So, on the top ten, the connection occurs (after I removed the "Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)" checkbox on the server in Remote Settings, but the remote server swears: "The user name or password is incorrect . Try again."
What am I doing wrong? The options "you enter the wrong login password" are not considered.

Answer 1

How do you specify the username? By default, 10 issues a local user there, i.e. the domain puts the name of a computer.
Specify the username as \administrator
i.e. with an explicit empty domain

Answer 2

In addition to the option not considered, this error can be caused by the following reasons:
1. The remote user on the server has not been assigned a password;
2.The user is not an administrator, or the user is not a member of the Remote Desktop Users group.
In general, it is strange that I had to turn off "Network Level Authentication". The option to disable this setting is intended for older WinXP clients. In Win10, the client definitely supports this (in fact, it already worked in Win7).
